Azure Stack will be a disruptive, game changing technology

2016-08-29 - By 

Few companies will use pure public or private cloud computing and certainly no company should miss the opportunity to leverage a combination. Hybrids of private and public cloud, multiple public cloud services and non-cloud services will serve the needs of more companies than any single cloud model and so it’s important that companies stop and consider their long term cloud needs and strategy.

Providing insight into the future of cloud computing is something that Pulsant has a lot of experience in and our focus on hybrid IT and hybrid services allows us to see where the adoption of public and private cloud benefits our customers’ strategies and requirements.

Since so much of IT’s focus in the recent past (and in truth, even now) has been on private cloud, any analytics that show the growth of public cloud give us a sense of how the hybrid idea will progress. The business use of SaaS is increasingly driving a hybrid model by default. Much of hybrid cloud use comes because of initial trials of public cloud services. As business users adopt more public cloud, SaaS in particular, they will need more support from companies, such as Pulsant, to help provide solutions for true integration and governance of their cloud.

Game changer

The challenge, as always in the cloud arena, is that there is no strict definition of the term ‘hybrid.’ There has been, until recently, a distinct lack of vendors and service providers able to offer simple solutions to some of the day-to-day challenges faced by most companies who are trying to develop a cloud strategy. Challenges include those of governance, security, consistent experiences between private and public services and the ability to simply ‘build once’ and ‘operate everywhere’.

Enter Azure Stack — it’s not often that I use language like “game changing” and “disruptive technology” but in the case of Azure Stack I don’t think these terms can be understated. For the first time you have a service provider (for that’s what Microsoft is becoming) that is addressing what hybrid IT really means and how to make it simple and easy to use.

So what is Azure Stack?

This is the simple question that completely differentiates Azure (public) / Azure Stack from a traditional VM-based environment. When you understand this, you understand how Azure Stack is a disruptive and game changing technology.

For a long time now application scalability has been achieved by simply adding more servers (memory, processors, storage, etc.) If there was a need for more capacity the answer was “add more servers”. Ten years ago, that still meant buying another physical server and putting it in a rack. With virtualisation (VMware, Hyper-V, OpenStack) it has been greatly simplified, with the ability to simply “spin-up” another virtual machine on request. Even this is now being superseded by the advent of cloud technologies.

Virtualisation may have freed companies from the need for having to buy and own hardware (capital drain and the constant need for upgrades) but with virtualisation companies still have the problem of the overhead of an operating system (Windows/Linux), possibly a core application (e.g. Microsoft SQL) and, most annoyingly, a raft of servers and software to patch, maintain and manage. Even with virtualisation there is a lot of overhead required to run applications as is the case when running dozens of “virtual machines” to host the applications and services being used.

The public cloud takes the next step and allows the aggregation of things like CPUs, storage, networking, database tiers, web tiers and simply allows a company to be allocated the amount of capacity it needs and applications are given the necessary resources dynamically. More importantly, resources can be added and removed at a moment’s notice without the need to add VMs or remove them. This in turn means less ‘virtual machines’ to patch and manage and so less overhead.

The point of Azure Stack is that it takes the benefits of public cloud and takes the next logical step in this journey — to bring the exact capabilities and services into your (private) data centre. This will enable a host of new ideas letting companies develop a whole Azure Stack ecosystem where:

  • Hosting companies can sell private Azure Services direct from their datacentres
  • System integrators can design, deploy and operate Azure solution once but deliver in both private and public clouds
  • ISVs can write Azure-compatible software once and deploy in both private and public clouds
  • Managed service providers can deploy, customise and operate Azure Stack themselves

I started by making the comment that I thought Azure Stack will be a disruptive, game changing technology for Pulsant and its customers. I believe that it will completely change how datacentres will manage large scale applications, and even address dev/test and highly secured and scalable apps. It will be how hosting companies like Pulsant will offer true hybrid cloud services in the future.
